To @ZZ whom t may comme:

Be 1t known that DovvLING BnnJAMiN, a citizen of the United States, residing; oe

Camden, in the couniiy of Camden eno. Siete of New Jersey, have invente@L certain new and useful improvements in Compound Safety-Seal. Condensing-Caps, of which the following is o speoiication.

My invention relates to improvements in compound safety-Soavi 'condensing oops, and

more particularly to a oep of the character stated for the radiators of entomobiies, the

object;v of the invention being to provide e cold Weather, a certain neroentage of oleoliolis mixed With the Water io prevenJ freezing and this elcolioi renders the fluid. verf,T volatile, so thor, it veporizes from the nene -offthe engine. With the orciinary construe- 'on oi radiatori such vapor would escape tlirough the outlet or overflow pipe, Wherees with my improvements the vapor would be condensed and returned in iiquid forno. vo the racliaior.

A iurther object is to provide e oep oi' one character stated which permits on escape o i sibeeni when the pressure reaches e pre-eiferininerl degree, and which also prevents elle occurrence or' partial vaouum Within the radiator.

A. furlslierobjeot is to provide a oep of the character stored which permits a oiroulation of ooicl air aronn the seine-.While the eutomobiieis running or standing stili, so :that the operation of vopor condensation is carried on at eli times.

1With these and other objects in view, the invention consists in certain novel features of construction anni combinations and errangemens or ports :is Willi loe more fully i1ereinazerrlesfsribeofanni pointed ont in the claims.
